- Abstract
- This paper summarizes dynamic characteristics of five buildings within the San Francisco Bay area. The dynamic characteristics are extracted from the October 17, 1989 Loma Prieta earthquake response records and from ambient tests conducted in November 1990. Dynamic characteristics determined for two of the five buildings prior to the Loma Prieta eqrthquake are also included for comparison. The results are to be used to draw conclusions related to the validity of small amplitude tests in assessing the dynamic characteristics of buildings and other structures. The preliminary results show, in some cases, that low-level tests are useful and, in other cases, they show considerable differences with those determined from strong-motion response records.
